Material overview
S355J2W is an EN weathering-steel designation. Use the complete grade, delivered condition and thickness range when ordering; the “J2” requirement should remain explicit in the project specification.
Specification checkpoints
| Item | What to specify |

Prepare the order details
Identify the required dimensions in millimeters, quantity in pieces and any tolerances beyond the agreed product standard. For shaped parts, include the drawing revision, cutting allowance and visible-face requirements.
- Thickness × width × length, with quantities for every size
- Mill finish, natural weathering or a separately agreed treatment
- Delivered condition, identification and inspection records
- Site exposure, intended application and drainage considerations
- Destination, delivery basis, packing and requested schedule
Processing methods, achievable sizes, sample approval and lead time are reviewed against the actual requirement. No fixed stock or capacity is implied by this page.
Application references
- Structural fabrication
- Bridge-related plate inquiries
- Exposed steelwork
The final material decision belongs to the project specification. A grade or finish alone does not establish suitability for a particular structure or exposure.
